TECHNICAL FIELD

This disclosure concerns filter arrangements and methods. In particular,this disclosure concerns spin-on filter assemblies for filteringliquids, such as fuel, lubrication fluids, such as oil, and hydraulicfluids.

BACKGROUND

Conventional spin-on filter designs use a thread plate at the interfaceend of the filter assembly. This thread plate has flow passages to allowflow in and out of the filter assembly. In addition, there is often anattaching feature near the center line of the filter assembly wherethreads on the thread plate engage threads on the filter head.

An alternate design is what is sometimes referred to as a “big mouth”filter. In such “big mouth” filters, the thread plate is replaced with athreaded ring. The attaching feature is near the outside diameter of thefilter assembly. This design reduces the overall amount of material andis structurally stronger than the thread plate design. The big mouthdesign has the flexibility of using either internal or external threads.Internal threads are typically used on applications that accept either aspin-on or a bowl/cartridge design. The threaded ring mentioned above,uses internal threads.

Using external threads for a spin-on filter presents technical issuesbecause the typical seaming process used with a threaded ring can not beused. Improvements are desirable.

DETAILED DESCRIPTION

In general, a filter arrangement in accordance with principles of thisdisclosure uses a drawn metal housing, a threaded sleeve and seals. Thethreaded sleeve is slid over the outer diameter of the housing and issecured, in various techniques, to the housing. There is at least oneseal on the filter arrangement to prevent external leaks between thefilter arrangement and the filter head. In some implementations, morethan one seal member is utilized.

A. Example Constructions

In general, a filter arrangement is shown at reference numeral 20. Thefilter arrangement 20 is designed for threadably securing to a filterhead 22 (FIG. 12). In general, the filter arrangement 20 is threadedonto the filter head 22 for operable use. When it is time to service thefilter arrangement 20, the filter arrangement 20 is removed from thefilter head 22 by unscrewing or unthreading the filter arrangement 20from the head 22. The filter head 20 includes a housing 24. The housing24 is typically a drawn metal housing having generally a thin-walledconstruction. The housing 24 includes a surrounding wall 26 defining aninterior volume 28.

At one end of the housing 24 is an open mouth 30 providing access to theinterior volume 28. Opposite of the open mouth 30 is an end 32. In someembodiments, such as FIGS. 1-11, the end 32 defines an opening 25adapted to receive other structure such as a drain valve. In otherembodiments, the end 32 can be a closed end and is not operablyopenable.

Within the interior volume 28 of the housing 24 is a filter mediaconstruction 36 (or filter cartridge 36). The filter media construction36 may include pleated media 38 arranged in a cylindrical form to definean open filter interior 40. A first end cap 42 is secured to one end ofthe pleated media 38. In some arrangements, a second end cap 44 issecured to an opposite end of the pleated media 38. The filter mediaconstruction 36 may also include an inner filter support or liner 46,extending between end cap 42 and second end cap 44, and lining the openfilter interior 40.

In general, liquid to be filtered, flowing in a forward-flow manner,flows from a volume 48 between the wall 26 and the pleated media 38,through the media 38, and into the open filter interior 40. From there,the filtered liquid flows out through an aperture 50 in the first endcap 42. From there the liquid is directed into the filter head 22, whereit is then directed to downstream components.

In example embodiments illustrated, the filter media construction 36further includes a filter element seal member 52 to provide a sealbetween the unfiltered side and the filtered side of the filter mediaconstruction 36. The filter element seal member 52 will be sealedagainst a corresponding portion on the filter head 22. In the variousembodiments shown, the filter element seal member 52 is depicted as aseal ring 54 that is held within a radial groove 56 of an axiallyextending portion 58 of a first end cap 42.

In some implementations, the filter media construction 36 may furtherinclude structure to help with centering the filter media constructionwithin the housing 24. This is described below, in connection withcertain embodiments.

In general, the filter arrangement 20 includes a sleeve 60, distinctfrom the housing 24. By the term “distinct from the housing,” it ismeant that the sleeve is not made from the same piece of material as thehousing 24. While the sleeve 60 can be molded onto the housing 24, itshould be understood that the housing 24 exists as a separate piecebefore the molding process, and therefore, the sleeve 60 is distinctfrom the housing 24.

The sleeve 60 is secured to an exterior 62 of the surrounding wall 26and adjacent to the mouth 30. The surrounding wall 26 also has anopposite, interior 64. The sleeve 60 extends partially along theexterior 62 of the surrounding wall 26, generally less than half of thelength of the surrounding wall 26. The sleeve 60 has an exterior 66 andan opposite interior 68.

In general, the exterior 66 of the sleeve 60 defines mounting threads 70constructed and arranged to removably mount with the filter head 22,when the filter arrangement 20 is secured to the filter head 22. Thethreads 70 can be any type of conventional thread utilized in thesetypes of systems, such as Unified Screw Threads, per ANSI B1.7M-1984.The interior 68 of the sleeve 60 is generally mounted against theexterior 62 of the surrounding wall 26. The sleeve 60 is secured to thehousing 24, utilizing various techniques, as described below.

In general, the filter arrangement 20 further includes a first sealmember 72 oriented against the sleeve 60 to create a seal with thefilter head 22, when the filter arrangement 20 is secured to the filterhead 22. The first seal member 72 can be a radially directed seal member74 held by a groove 76 in the exterior 66 of the sleeve 60 such asdepicted in the embodiments of FIGS. 3, 10, 16, and 22.

The filter arrangement 20 can be connected to the filter head 22 to forma filter assembly 23, as shown in FIG. 12. In FIG. 13, a system is shownat 170. The system 170 includes an engine 172 utilizing a liquid. Theliquid can be, for example, lubrication, fuel, or a hydraulic fluid. Thefilter assembly 23 is in fluid communication with the engine 172 tofilter the liquid that utilized by the engine 172.

1. The Embodiments of FIGS. 1-11

In the embodiment of FIGS. 1-11, the housing surrounding wall 26 has aplurality of tabs 82 extending radially outwardly from the open mouth30. In the embodiment shown, the tabs 82 are evenly spaced about the rim84 of the mouth 30. The tabs 82 are illustrated as being curved to forma hook-shape 86, FIG. 8. The sleeve 60 has a first rim 88. When thesleeve 60 is passed over the wall 26 of the housing 24, it is movedaxially along the wall 26 until the first rim 88 engages a radiallyextending flange 90 at the mouth 30. The sleeve 60 is rotated relativeto the housing 24 until slots 92 defined by the sleeve 60 along thefirst rim 88 line up with the tabs 82.

The tabs 82 are then crimped in a radially direction toward the housing24 center line to affix the housing 24 and the threaded sleeve 60together. Crimping the tabs 82 into the slots 92 creates a mechanicallock between the housing 24 and the threaded sleeve 60, which preventsthe housing 24 from turning about its center line relative to the sleeve60 and prevents relative motion in an axial direction.

In FIG. 5, it can be seen how the sleeve 60 defines a seal gland 94along the sleeve interior 68. The seal gland 94 holds a seal member 96,which forms a radial seal 98 between and against the sleeve 60 and theexterior 62 of the surrounding wall 26.

In FIGS. 4 and 10, it can be seen how the filter media construction 36is centered in the housing 24 by a series of guides 102 that are locatedcircumferentially around the outer diameter of the first end cap 42. Theguides 102 ensure that the center line of the filter media construction36 is within acceptable tolerance of the center line of the housing 24.

In this embodiment, the filter media construction 36 is retained in thehousing 24 by crimping a lower end 104 of the housing 24 into a recessedarea 106 that is defined by the outer surface of the second endcap 44.

2. The Embodiments of FIGS. 14-20

In the embodiment of FIGS. 14-16, many of the features and componentsare the same as described with respect to the embodiment of FIGS. 1-11.To this extent, the same reference numerals are used for analogousfeatures, and their descriptions are incorporated herein by reference.The filter arrangement depicted in FIGS. 14-20 is shown at referencenumeral 220. Note that in the embodiment of FIGS. 1-11, a plurality oftabs 82 fold down over the top of the threaded ring or sleeve 60. In theembodiment of FIGS. 1-11, the tabs 82 are used to both hold the sleeve60 axially to the housing 24 and also rotationally to the housing 24,such that the sleeve 60 would not rotate about the housing 24. Also notethat in the embodiment of FIGS. 1-11, there is a seal member 98 locatedbetween the interior 68 of the sleeve 60 and the exterior surface 62 ofthe housing 24.

In the embodiment of FIGS. 14-20, a seam 221 results from one continuouspiece of material, rather than the plurality of tabs 82 shown in FIGS.1-11. The seam 221 holds the sleeve 60 axially relative to the housing24. To prevent rotation of the sleeve 60 relative to the housing 24, thesleeve 60 can be press fit to the outer diameter of the housing 24;alternatively, the sleeve 60 can be glued to the outer diameter of thehousing 24 by using glue or adhesive between the exterior 62 of thehousing 24 and interior 68 of the sleeve 60.

A seal member 223 is oriented on the outside diameter of the sleeve 60,near a top 224 (FIG. 16A) of the sleeve 60. The seal member 223 is heldwithin a groove 225 (FIG. 16A) defined by the sleeve 60. The groove 225faces the exterior or outside portion of the sleeve 60. The seal member223 creates a seal 226 between the sleeve 60 and an inside curve 227 ofthe seam 221, which is one continuous piece of material. Typically, theseam 221 will be formed from a drawn metal, such as steel. The seal 226prevents liquid from leaking between the housing 24 and the sleeve 60.

In FIG. 16A, it can be seen how, in this embodiment, the seam 221 isformed by bending or folding the housing 24 to form an upside downu-shaped bend 228, which also forms the open mouth 30 of the housing 24.The u-shaped bend 228 terminates with an inwardly extending leg 230. Theleg 230 locks around projection 232 of sleeve 60, in order to help lockthe seam 221 in place with the seal member 223 trapped and securedwithin the groove 225.

Adjacent to and below the projection 232 of the sleeve 60 is a flange234 projecting radially from the sleeve 60. The flange 234 forms oneside of a groove 236, which holds the seal member 74.

FIGS. 19, 20, and 19A illustrate a filter assembly 240, which includesfilter arrangement 220 secured to filter head 222. FIG. 19A shows howseal member 74 creates a seal 236 between the sleeve 60 and the filterhead 222; specifically, between the sleeve 60 and an inside wall 238 ofthe filter head 222.

In FIG. 19, it can also be seen how the seal member 54 creates a seal 55between the filter cartridge 36 and the filter head 222; specifically,between the end cap 42 and an internal wall 242 in the filter head 222.The internal wall 242 is circumscribed by an outer wall 244. The outerwall 244 defines the internal surface 238, which forms seal 236 with theseal member 74. The wall 244 also, in this embodiment, includes internalthreads, which mate with threads 70 on the sleeve 60, to provideremovable attachment of the filter arrangement 220 to the filter head222.

In FIG. 20, the filter head 222 is shown having ports 246, 248. Theseports 246, 248 form either inlet or outlet ports. Fluid to be filteredflows through one of the ports 246, 248, and then into the volume 48between the wall 26 and the media 38. From there, the liquid flowsthrough the media 38, and into the open filter interior 40. From there,the filtered liquid flows out through the aperture 50 in the first endcap 42, and then exits the assembly 240 through one of the ports 246,248.

In FIG. 20, it can be seen how a twist-valve structure 250 can beoriented in the opening 25 to allow for selective draining of water orother types of fluid that is collected in the housing 24 after a periodof use.

FIG. 18 shows a perspective, exploded view of the housing 24 and sleeve60, during the assembly process. In FIG. 18, it can be seen how prior toseam 221 being formed, it has the configuration of a flat flange 252.The sleeve 60 is mounted around the housing 24, such that the internalsurface 68 of the sleeve 60 is against the exterior 62 of the housing24. The sleeve 60 may be secured rotationally to the housing 24 by, forexample, press fitting the sleeve 60 to the housing 24, or by adheringthe sleeve 60 to the housing 24 using glue or adhesive. After the sleeve60 has been located on the housing 24 and positioned such that the end224 is engaged against inside axially surface 254 of the flange 252, theflange 252 is bent to form upside down u-shaped bend 228, which coversthe seal member 223 and forms seal 226. This forms the seam 221. The leg230 is bent against the projection 232 to help axially lock the sleeve60 relative to the housing 24.

3. The Embodiment of FIGS. 21-24

FIGS. 21-24 show another embodiment of a filter arrangement, showngenerally at 320. Again, in this embodiment, the same reference numeralsindicate parts with analogous features as described above with respectto FIGS. 1-20. In this embodiment, as compared to the embodiment ofFIGS. 16-20, the design is analogous except that the functions of sealmember 223 and seal member 74 are combined into a single seal member322. The seal member 322 provides a seal 324 (FIG. 23A) with filter head222; it also creates a seal 326 between the housing 24 and the sleeve60.

The seam 321 is formed by bending or folding a continuous piece ofmaterial, such as the housing 24, over the end 224 of the sleeve 60.This sleeve 60 defines a groove 330, which holds the seal member 322.The seam 321 is bent around the end 224, down along the outside radiallysurface 332 of the sleeve 60, and then radially inwardly into an upperwall 334 of the groove 330. The leg 336 extending within the groove 330and against the upper wall 334 helps to axially lock the sleeve 60 tothe housing 24. The seal 326 is created between and against the sealmember 322 and the leg 336 of the seam 321.

B. Methods
